My chicks just turned a month old and I was very excited but I've since realized that many of them are sneezing. They seem like dry sneezes and there are not other symptoms of anything but I'm worried and would love some advise. I've been reading other posts and I've been getting mixed answers (duramycin, natural remedies, etc). Should I give antibiotics, if so what type (not too knowledgeable on that) or should I try natural remedies (if so, can you recommend any)? Thanks, in advance.
